India and China are back to sparring over territorial claims involving Arunachal Pradesh and Aksai Chin.        

It all started with the Chinese government showing Arunachal and entire Aksai Chin as part of its territory in maps of the country on their new e-passports.        

Unhappy at this, the Indian embassy in Beijing is said to be issuing visas to Chinese nationals with a map of India showing Arunachal and Aksai Chin as its territories.        

After the water marks in the new Chinese e-passports showed Arunachal and Aksai Chin as part of China, the Indian mission started issuing visas with Indian maps including these places as part of its territory.
